Brief summary

Aim 1. Determine the impact of a daily, automated telephone intervention on HbA1c levels compared to standard care in older patients with type 2 diabetes. Aim 2. Determine the impact of the automated telephone intervention compared to standard care on adherence to prescribed SMBG frequency in older patients with type 2 diabetes. Aim 3. Determine the impact of the automated telephone intervention compared to standard care on self-reported diabetic control problems in older patients with type 2 diabetes. Aim 4.
